MEANS vFORlllCRl-ASING THE FLOW AND DELIVERY OF LIQUIDS.

SPECIFICATION forming part of Letters Patent No. 286,185, dated October9, 1883.

` Application med April a, issn. (No model.)

To all whom it may concern:

Be it known that I, JOHN L. DoUGLAss, of Belleville, in the county ofEssex and State of New Jersey, have invented certain new and usefulImprovements in Means for Increasing the Flow and Delivery of Liquids,of which the following is such a full, clear, and exact description aswill enable others skilled in the art to which my invention appertainsto construct and use the same, reference being had to the accompanyingdrawings, forming part of this speciiication.

The object of my invention is to produce, by suitable means, in anaqueduct, conduit, sewer, pipe, or course a flow of water or otherliquid greater in rapidity, and consequently (within a given period)greater in bulk, than would be ceca ionel by the force of gravitationalone; and I accomplish this purpose by the use of wheels, endlessscrews or worms, fans, chainbuckets, or other suitable mechanismarranged and operated as hereinafter described.

In the drawings, Figure 1 shows engines or other motive power, locatedat suitable distances apart along the course oi an aqueduct or otherchannel, for operating the wheels or other means employed for producingthe increased Iiow ot water or other liquid. Figs. 2, 3, and et and A BC D E show wheels, fans, or other contrivances, which, by theirrevolution or movement in the liquid,aceelerate and increase the flow ofthe same 5 and Fig. 5 represents the general course of an aqueduct orchannel, with such engines and other mechanism located and operated asherein described. Enlargements, widenings, or additional means or"communication in the course ot' the aqueduct or channel, examples ofwhich are shown in the drawings, for the purpose hereinafter named, mayalso be made with advantage. The lowest, or the one nearest the outletof the wheels or fans, being set in motion in the stream bypineans ofany suitable power connected by bevelgearing, cranks, or otherwise, `amore rapid and greater flow of liquid will thereby be caused therein,such i11- crcase ot' ilow extending up or back from the exit or outfall.until the suction and consequent acceleration of the speed of thestream. produced by the revolution of the wheel shall have becomeexhausted or diminished. A second wheel or fan is inserted in the streamat the point found most effective or desirable, and operated bymechanism in like manner at a suitable velocity, thereby producing acontinued suction and increased ilow operating in the direction of itsoutlet upon the column or stream of liquid above the wheel. Additionaland further wheels or other mechanical appliances and the requisitemachinery for operating the same are or may also be used in continuationof the series, according to the length of the stream or liquid column,and as may be necessary to fully accomplish the purpose of increasingthe flow so as to obtain the required amount of water or other liquidwithin a given time. The wheels or appliances for moving the liquid morerapidly may be made to revolve or work at different rates of speed,according to the varying gravitation of the liquid at different points,or in. case a greater bulk of suchV liquid" can be delivered by suchvariations in the motion ofthe wheels. There may also be enlargements ofthe channel, pipe, or conduit at or below the points where the wheels orappliances act upon the liquid. Such enlargements will avoid anycrowding or tendency of the liquid to ow in a backward direction.

I am aware` that heretofore an improvement in sewers has been made andpatented in which a branch sewer isV constructed for the purpose ofcarrying off the overflow occasioned by high water or other causes, andthat, in connection with such construction, a paddle or fan wheel waspivoted in an enlargement or chamber in the top of the sewer, at acertain dis` tance above the said branch, by means of the revolution ofwhich wheel an impulse is given the overflowing sewage, so as to assistit in passing up and out through the branch sewer; but my invention isdistinct therefrom, and consists of a series of wheels or other suitableappliances operating simultaneously and directly upon the body of theliquid, so as to augment and accelerate an existing downward -2 y eselsioW. -I do not therefore claim a device simiences arranged lsind adaptedtobe operated by lar to the above-named improvement in seW- power, andto simultaneously actdirectly 'upon 1o ers; but the body of the liquid7substantially as and What I do claim as new, and desire to sefor thepurpose herein set forth. 5 cure by Letters Patent, is- JOHN L.DOUGLASS.
